Okay. What Trump painted as a future (And probably not THAT far in the future) step, the compete wipeout of a nation, is that kind of war crime that would set him - and the USA as a whole - on a level with Saddam, Assad, etc. And as the situation with Korea is as it is, it would include the wipeout of South Korea, too
If that is what you find acceptable, in a way of being the "Tough Guy"... you are mad, too.
North Korea is extremely dependent on China and thus, as it cannot stand on its own feet, is very steerabe by diplomatic ways. It's just not working in the schoolyard politics the Trump administration uses. This is so stupid I feel more pity for you as a country, but you are like a toddler playing with a shotgun.
And that is why we can be glad the Mueller investigations are going well, now it looks he needs to step it up, to save what is left of your country.
